Exam 13: Tectonics, Earthquakes, and Volcanism

Human populations are growing in areas prone to seismic activity and near active volcanoes.

Orogens are markably well correlated with the plate tectonics model.

The Sierra Nevada and Grand Tetons are examples of tilted-fault block mountain systems.

A hypsographic curve is

I an oceanic plate-continental plate collision, denser continental crust dives beneath oceanic crust.

Large areas of high tablelands are found in

A topographic region that is characterized by local relief of more than 600 m (2,000 ft) is a

An active volcano is defined as one that

Small surface irregularities along a fault plane that prevent movement and are generally areas of high strain are termed

In a normal fault, the hanging wall drops (moves downward) relative to the footwall.

Explosive eruptions produce composite volcanic peaks and few lava flows.

An active volcano is one that has erupted at least once in the last 25 years.

History seems to teach us that humans are generally unable or unwilling to perceive hazards in a familiar environment.

Circular surface depressions usually found at or near the summit of a volcano are known as

Paleoseismology estimates expected earthquake activity based on past earthquake activity.

Discuss the process and causes of folding, and distinguish between anticline and syncline.

The nucleus of old crystalline rock in each of the principal continental masses is called a

A gently sloping mountain landform built from effusive eruption is known as a

Describe the three orders of relief and give one example of each.

The Alps are examples of the second order of relief.
